These pens are the following, pictured from top to bottom in the photo below: Pilot G-Tec-C Maica, Pilot Birdie Ballpoint, and Pilot Fineliner.
The Pilot G-Tec-C Maica, as the name suggests, takes G-Tec-C refills and packages them in a slightly more interesting barrel. It is all plastic except for the part that unscrews and reveals the refill. The cap has no clip, but has a tiny protrusion to keep the pen from rolling off the table. I think this protrusion is meant to look like the handle of a teacup. The end of the cap also has some shiny material that makes it look like a gem, and the overall feel of the pen is something royal or princessy. It also comes in a good range of colors.
The Pilot Birdie Ballpoint is an all-metal pen and is really slim and tiny. I bought this mostly to fit in a Leuchtturm penloop, but it turns out that it actually writes pretty well. The tip is revealed by clicking on the knocker. The clip is quite serviceable.
Both the Maica and the Birdie Ballpoint are available at National Bookstore. The Birdie is only available in select branches, and you have to ask over the counter for it. Refills are also readily available for both pens.
The Pilot Fineliner is one of the items that I got in a Maker Monthly box. It is a felt tip marker that has a certain amount of give, and you can actually achieve a sort of brush calligraphy with this pen because of that. The pen is made mostly of plastic, except for the clip. As far as I know, this pen is not available locally.
All three pens write beautifully. As I mentioned earlier, I am a big fan of fine tipped pens, and both the Maica and the Birdie produce a tolerably fine line. I think the Maica comes in a narrower tip, but the 0.4 works pretty well for me. The G-Tec-C refill is excellent and rarely skips. The Birdie on the other hand has some starting issues, and can sometimes skip.
The Fineliner produces a pretty pigmented black, and with my regular hand can even produce a relatively fine line. I like using this marker for writing addresses on snail mail, and for making small brush calligraphy.
